Definitions

  • the invention relates to the use of derivatives of tetrahydro isoquinoline for the preparation of an anti-tumor medicament and in particular of an anticancer medicament, the application as medicaments of derivatives of tetrahydro isoquinoline and derivatives thereof of this structure.
  • oncogenes in a mammalian cell leads to the transformation of normal cell types into cancer cells. Said transformation is caused by the infection of a cell by a retrovirus.
  • a retrovirus We can cite as a well-known example the infection of chickens by the Rous virus which leads to the appearance of cancer.
  • the corresponding oncogene which is responsible for the malignant transformation has been called the "SRC" gene (JS Grugge RL Erikson, Nature 269 , 346-348 (1977).
  • oncogenes are characterized by the expression of a protein possessing kinase activity. These enzymes catalyze the transfer of the terminal phosphate group from ATP to an amino acid. Unlike many other proteinkinases which transfer the phosphate group to a seryl or threonyl residue, most oncogenic kinases phosphorylate a tyrosyl residue from the protein chain. Furthermore, it is known that the products of oncogenes, namely those of the oncogenes v-mos, v-mil and v-raf, have a specific serine / threonine proteinkinase activity (K. Rölling et al., Nature (London) 312 , 558-561 (1984), B. Singh et al., Journal of Virology 60 , 1149-1152 (1986).
  • Tyrosinekinase activity is an integral part of the function of certain growth factor receptors. New results show that the growth of many tumors depends on the presence of growth factors such as the Epidermal Growth Factor (EGF) "Transforming Growth Factor Alpha (TGFAlpha) or the “Platelet Derived Growth Factor (PDGF) (AS Goustin, GD Shipley, HL Moses, Cancer Research 46 , 1015-1029 (1986). As a consequence of the binding of growth factor with its receptor, the tyrosinekinase which is a proper component of the growth factor receptor, is stimulated.
  • EGF Epidermal Growth Factor
  • TGFAlpha Transforming Growth Factor Alpha
  • PDGF Platinum Derived Growth Factor
  • a tyrosinekinase and also serine / threoninekinase inhibitor can inhibit tumor growth and proliferation and can be used in anti-tumor therapy.
  • the products of formula (I) as defined below are inhibitors of oncogenic kinases such as tyrosinekinase, serine / threoninekinase and tyrosinekinase of the growth factor receptor and are therefore usable for the treatment of tumor diseases.
  • the products of formula (I) which have anti-proliferative, anti-oncotic and carcinostatic properties can in particular be used to inhibit tumor growth and proliferation and in tumor therapy.
  • the subject of the present invention is the use of the products of general formula (I): in which : X represents a hydrogen atom and Y represents a radical: in which R 'and R'1 are such that: or else they are identical and each represents a hydrogen atom or a hydroxy radical, or else they are identical or different and each represents an alkoxy radical having from 1 to 4 carbon atoms, preferably methoxy and Ar represents a radical: in which R2 and R3, which are identical or different, represent a hydrogen atom or an alkyl radical having from 1 to 4 carbon atoms, preferably methyl, and R1 represents a hydrogen atom or a methyl radical, as well as their addition salts with mineral or organic acids for the preparation of an anti-tumor medicament.
  • Products which have an asymmetric carbon can of course be in racemic or optically active form.
  • R 'and R'1 mention may be made, in addition to the hydrogen and hydroxy values, of the methoxy, ethoxy, propyloxy, isopropyloxy, butyloxy, isobutyloxy, tert-butyloxy values.
  • the addition salts with mineral or organic acids can be, for example, the salts formed with hydrochloric, hydrobromic, nitric, sulfuric, phosphoric, acetic, formic, propionic, malonic, maleic, fumaric, succinic, tartaric, citric acids. , oxalic, glyoxylic, aspartic, alkanesulfonic such as methane or ethanesulfonic acids, arenesulfonic, such as benzene or paratoluene sulfonic and arylcarboxylic acids, such as benzoic.
  • the preferred salts are the hydrochlorides, hydrobromides and acetates.
  • the medicaments which are the subject of the present invention may be in the form of pharmaceutical compositions intended for administration by the digestive, parenteral or local route. They can be prescribed in the form of simple or coated tablets, capsules, granules, suppositories, injections, ointments, creams, gels, which are prepared according to the usual methods.
  • the active ingredient (s) can be incorporated therein into excipients usually used in these pharmaceutical compositions, such as talc, gum arabic, lactose, starch, magnesium stearate, cocoa butter, aqueous vehicles or not , fatty substances of animal or vegetable origin, paraffinic derivatives, glycols, various wetting agents, dispersants or emulsifiers, preservatives.
  • excipients usually used in these pharmaceutical compositions such as talc, gum arabic, lactose, starch, magnesium stearate, cocoa butter, aqueous vehicles or not , fatty substances of animal or vegetable origin, paraffinic derivatives, glycols, various wetting agents, dispersants or emulsifiers, preservatives.
  • the dosage varies depending on the condition to be treated and the route of administration, it can vary for example from 10 to 500 mg per day in adults by oral route.
  • the usable dose can be 50 to 250 mg per day orally.
  • a subject of the invention is also, as a medicament, 3-phenylmethyl 1,2,3,4-tetrahydro isoquinoline 6,7-diol and 3 - [(3,4-dihydroxyphenyl) methyl] 1,2,3 , 4-tetrahydro isoquinoline 6,7-diol and their salts with pharmacologically acceptable mineral or organic acids.
